SRFirewall is an easy to use, but still quite capable firewall for Netfilter/iptables. It is a complete rewrite of Firewall/SOSDG, designed to make it easy for users to configure and protect their Linux servers, routers, and gateways.

Oolite is an independent reinterpretation and ehancement of the classic space sim game Elite for modern computers. The result is a space trading and combat simulation offering encounters with pirates, police, bounty hunters, the occasional alien menace, and other surprises along the way. While striving to reach the coveted Elite status, the players set their own path through the various galaxies, choosing to be trader, pirate, or bounty hunter depending on the situation at hand, and their own judgement. The game is hugely expandable, using a combination of property lists and JavaScript. Oolite's active modding community already provides more than 200 OXPs (Oolite eXpansion Packs). Among them are a huge variety of missions, weapons, ships, and extra career paths over and above what's available within the core game, as well as a number of other gameplay enhancements and customizations.

Shard Linux is a minimal, lightweight Linux distribution, built upon Debian Netinstall Minimal. It uses the XFCE window manager. Each library and package was added by hand, and no meta-packages were used at all.

rules2mrtg is a tool that creates MRTG data traffic graphs derived from iptables's internal traffic statistics for the local machine for every configured IP number/ethernet alias. You can also define ports or port ranges to be monitored per IP address. This avoids problems with using SNMP and aliased interfaces.

Surealived is a effective LVS (Linux Virtual Server) service tester. It is based on epoll and allows you to detect your hosts' state using HTTP, TCP, DNS, exec, and a universal LUA embedded tester. SSL is also supported. Testers are dynamic modules, and you can extend and write your own modules. You can also dynamicaly change the weight or set real states at run-time. Test states are injected into the kernel IPVS table using the ipvssync application. Configuration is highly extensible, so many testing protocols can be implemented easily.

The overall objective of the XtreemOS project is the design, implementation, evaluation, and distribution of a grid operating system (called XtreemOS) with native support for virtual organizations (VO). XtreemOS is capable of running on a wide range of underlying platforms, from clusters to mobiles. It is based on Mandriva Linux, with support to come for other distributions later.

neko-install-cd is a development tool for modifying System Rescue CD images. It can also perform many other operations. It has a simple interface with excellent inline help. Operations it can perform include: booting your modified image in a virtual machine, burning the original or modified image to a USB drive, creating patch sets from your modifications (using aufs or built-in helper scripts). All of these operations can be performed directly from your Linux distribution, without having to first boot into the system rescue CD as with the system rescue CD equivalents.

filter_evdev creates a virtual input device from a physical input device. It provides anytime configuration of positive, negative, or custom acceleration or sensitivity for each axis, or remapping axes or buttons as requested, e.g. inverting the two main mouse buttons or making the middle button act as the right button. Configuration can be dynamically changed by text commands sent to a UNIX socket. Commands apply to specific axes, buttons, or keys when moved in specified value ranges, and consist of custom arithmetic operations.
